SPECIFICATION forming part of Letters Patent No, 563,813, datedd'uly 14, 1896.

Application filed August 5,1295.

To all whom it may concern.-

Be it known that I, FREDERICK W. sIEGEL,

a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Spring-Holding Chucks for Bottle-Washing Machines; and I do hereby declare the following to be a full, clear, andexact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. p

' The object of this invention is to prevent breakage of the springs which hold the wash-' ing-b'rush in bottle-washing machines, to secure a moreperfect adjustment of the'said portions of the same.

springs upon thechuck, and to prevent said springs, in the operationof adjusting them or fastening them in the chuck, fromturning out of position and thus becoming incapable of properly holding the brush. Further objects maybe referred to hereinafter in connection with the description of the Working parts.

The invention consists in the improved spring-holding chuck for bottle-washing machines and in the combinations and arrangements of parts, substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the views, Figure 1 is a front elevation of the improved chuck arranged in'a bottle-washing machine and havin g the springs which hold the brush arranged therein. Fig. 2 is a longitudinal section of Fig. 3 is a transverse section of the same,--taken at line as, a certain collar not being in place; and Fig. 4: is a similar section with said collar in place.

In said drawings, a indicates the spindle of the machine, which is provided on the lower end with a female thread a, into which the chuck-body-is screwed. 1) indicates said chuck -jbody having a threaded shank 1), adapted to engage the spindle and turn there with. Beneaththis threaded-shank the body of the chuck is made angular or otherwise formed to receive a wrench or other suitable end of said hearings to the other.

clines e are sodisposed. as to give to the sen-s1 No. 558,228. on model-l tool by which the said chuck may be removed from said spindle. Below this, again, the

body of the chuck is provided with another set of threads 12", adapted to receive a correspondingly-t-hreaded collar 0, and at its lower I line'is only suflicient to secure a firm grasp- .or binding of the collar upon the springs when saidcollar is brought down into position-.

' In the prior devices of which I am aware the spring-clamping parts presented plain circular surfaces devoid of recesses, and thus care was required to keep the springs in proper position on opposite sides of the inner member ofthe clamp, said springs being freeto move sidewise in the annular space between the partsun-til finally brought into firm clamping engagement by the screwing up of said parts.

The recesses 'b. b, lying on opposite sides of the inner or central member I) in the preseht case, are of a. width corresponding more or less closely with the width of the springs, so that when said springs are resting therein there can be no lateral movement, even though the clamps are not in final clamping relation. The sides of the lower extremity are also made slightly tapering, as at e in Fig. 2, to receive a correspondingly-tapering end of the collar,

by Which'means, when the collar is screwedup into position, it is brought hard upon the outer sides of the springs to hold them firmly against the chuck-body with great security and firmness.

The inclined bearings of the chuck-body and outside collar correspond or are parallel, and thus they lie hard against the opposite sides of the springs from one The inopposite springs an inward extension, as in Figal and 2, so that as they project down from the chuck they approach one another slightly. The springs thus normally approaching one another as they issue from the chuck may be pressed into contact with one another without any danger of breakage, said springs thu's dififeringfrom springsflflaring apart from one another at the point of issuance, in which construction the danger is increased and breakage frequent. Said collar is threaded at its upper end to engage the, body of the chuck-and at its lower end, on the interior, is slightly tapering or f unnel-shaped in correspondence with the taperin surfaces of the chuck-body. The springs; d extend out from the chuck in converging lines, after I which they turn outwardlyqto receive-the brush and press the same against the sides 013 the bottle. p q I I h Heretofore in chucks \for a similar purpose the chuck-body was hollow at its lower end to receive the springs and receive a screw plug or holder, which latter was inserted between the springs and projected below the extremity of the chuckvbody. When the two springs were. pressed togetherto admit of their flaringlower ends being inserted in the bottle. prior to the washing operation, the said pro-. jeeting plug served as a fulcrum over which the springs were pressed, the result of which construction was that the springs were fre 'quently broken, and very considerable. loss thereby occasioned. Furthermorayby such construction 4 the: springs were disposed in their relation to thechuck. so as to fiare immediatelyupon' their passing out from the chuck-body, and to secure the proper'operation the springs were *fiexedinoresharply and to a greater degree than bythe present con-z struction. This also, acting in connection with the projecting plug, served to produce, the breakage referred to. By iny improved construction these objections areall-avoided. Isecurea much more neat clamping of the 40 springs in their position and alsov additional.

firmness. vI avo d the breakage referred to,

and the springs d, by lying in the recesses, as described,'are prevented from working out of place when the fastening member is screwed up into position; I am able also to more maintaining-the adjustment, secure a proper disposal of the springs in their relative posie and combined, substantially as set forth.

2. The combination in awash-ing-machine,

ing; the water-passage 17", threads *1)", and, below saidthreads, opposite recesses b, the *lower end'of said chuck-body tapering to give an inward direction to the springs, said springs, acoll-ar and a brush, all arranged and combined, substantially as and for the pur- -posesset forth. L a v I In testimony that I claim the foregoing I have hereunto set myv hand this 30th day of July, 1895.
